Why do I have 2 connections when im using 1 client?

Question

The command:

select * from pg_stat_activity

shows all currently active connections. The database is hosted by AWS RDS and I am accessing the database with pgAdmin 4, thus I expect one other connection than mine and that is the rdsadmin, but it seems like I have 2 connections.

Output:

Why do I have two connections when using one Client?

Answer 1

The second connection gets started when you start the query tool.
